Abstract (en)
[origin: WO2014053261A1] An apparatus for encoding a speech signal by determining a codebook vector of a speech coding algorithm is provided. The apparatus comprises a matrix determiner (110) for determining an autocorrelation matrix R, and a codebook vector determiner (120) for determining the codebook vector depending on the autocorrelation matrix R. The matrix determiner (110) is configured to determine the autocorrelation matrix R by determining vector coefficients of a vector r, wherein the autocorrelation matrix R comprises a plurality of rows and a plurality of columns, wherein the vector r indicates one of the columns or one of the rows of the autocorrelation matrix R, wherein R(i, j) = r(Ιi—jΙ), wherein R(i, j) indicates the coefficients of the autocorrelation matrix R, wherein i is a first index indicating one of a plurality of rows of the autocorrelation matrix R, and wherein j is a second index indicating one of the plurality of columns of the autocorrelation matrix R.
